The 'Public Money - Public Code' campaign, as well as the 'REUSE Initiative' made me notice that the FSFE is an organization which supports the same ideals that I do. I want to help them do more great things, and so now I am proud FSFE supporter.
I hope that more and more people will understand the importance of being ethical in their digital life and thus consciously use Free Software and that we will have more and more volunteers from all over Europe.
I support the FSFE because it's totally worth it. Its community is strong and very knowledgeable on a wide range of topics, so contributing to its mission is a good way to help the Free Software movement.
Freedom in the information society needs your financial contribution.

Compression ratio
We compared 7-Zip with WinRAR 5.20.
FILE SETS: Mozilla Firefox 34.0.5 for Windows and Google Earth 6.2.2.6613 for Windows.
| Archiver | Mozilla Firefox | Google Earth | ||
|---|---|---|---|---|
| 65 files 85 280 391 bytes | 483 files 110 700 519 bytes | |||
| Compressed size | Ratio | Compressed size | Ratio | |
| 7-Zip 9.35 -mx | 39 357 375 | 100% | 15 964 369 | 100% |
| WinRAR 5.20 -m5 -s -ma5 -md128m | 41 789 543 | 106% | 17 035 432 | 107% |
Compression ratio results are very dependent upon the data used for the tests. Usually, 7-Zip compresses to 7z format 30-70% better than to zip format. And 7-Zip compresses to zip format 2-10% better than most of other zip compatible programs.
